As the social networking site is interactive and accessible to all netizens, including the space community worldwide, their comments, views, observations and suggestions will be welcome as much as constructive criticism.

"We will also post an update regularly on the health of the spacecraft despite 20-45 minute communication gap in receiving signals from the Orbiter and sending commands to it for manoeuvres due to the long distance and long journey towards Mars," Radhakrishnan pointed out.

Updating on the mission late Tuesday, the space agency posted that "all subsystems have been powered 'on' in orbit. Health of the spacecraft is confirmed normal".

About 90 minutes after Orbiter was injected into the Earth's elliptical orbit, one of the posts said, "Solar panel and reflector deployments have been completed successfully and the spacecraft has achieved the first orbit of 246.9 km perigee (nearest to Earth) and 23,566.69 km apogee (farthest from Earth)."

The spacecraft also made contact with the two terminals on board the twin ships Nalanda and Yamuna in the South Pacific Ocean near Fiji Island.

Indian cricket all-rounder Ravindra Jadeja was one of the earliest to post on the launch says: "ISRO's Mars mission is the cheapest so far, just 450 crore, i.e., 12 per km, equivalent to auto fare. Truly Indian."
